SHUTTER-FASTENER.

Application filed September 10, 1920.

T 0 aZZ w ham it may concern:

Be it known that I, Janus Y. VAN Bran:- COM, a citizen of the United States, residing at Paterson, in the county of Passaic and State of New Jersey, have invented cer tain new and useful Improvements in Shutter-Fasteners, of which the following is a specification.

The object of this invention is to provlde a shutter-bower o'r adjuster, of the class in which a shuttermay be bowed to any position or held fully open or closed, whereby the operations incident to-its use may be accomplished with facility and also with assurance that the shutter will remain securely held in any position to which it may be adjust-ed and whereby opening of the shutter from the outside will be prevented in certain positions of the parts, as where the shutter is partially closed as well as where it is fully closed, and which shall be simple in construction, comparatively inexpensive to manufacture and readily attachable as well as adapted to any. ordinary window frame and shutter.

One important feature of the invention is an arm pivotally connected at its ends to the frame and shutter and comprising longitudinally slidable sections so as to be extensible, and means to secure said sections to each other in any position to which they may be relatively adjusted. Another important feature consists in providing an arm section, suitably connected to the shutter, with such a pivotal connection with the frame that in one position of the shutter, as the fully closed position, such connection may be readily established or disestablished. but in any other position to which the shutter may be moved while said connection remains established it can not be disestablished, as by wind-movement of the shutter or by manipulation.

In the accompanying drawings,

Figure 1 shows a window frame and shut ter in section and my shutter-bower in plan;

Fig. 2 is an outside elevation of the window frame, the shutter and my shutterlfi ower, the shutter being fully open, as in Fig. 3 is a view like Fig. 1, but showing the shutter closed;

Fig. 4 is a section on line 4.i, 3; Fig. 5 is a view illustrating in detail the clamping means of the extensible arm;

Fig. 6 is a plan, partly in section, of the aforesaid connection between the arm and window frame; and

Fig. 7 is a plan of a certain wear-plate.

In said drawings, a designates the window frame and I) a shutter hinged therein in the usual way.-

On the shutter is a fitting, substantially L-shaped, its upper or vertical leg 0 being secured to the shutter by a screw and at the extremity bent away therefrom to form a fingergrip, and its horizontal leg rZ projectingfrom the shutter. and provided with an aperture 6 (in form preferably like aperturesc' to be referred to) and having pivoted to its free end an elongated button fwhich is about as wide as but longer than the leg is thick (see Fig. 2).

On the sill of the frame a is a bracket g which is slotted, as at it, so as to receive leg 'cZ when the shutter is closed (see Fig. 4) in which position the button f may be'turned to block withdrawal of the leg (Z from the bracket. Button f is an auxiliary means for so blocking withdrawal of said'leg, as will appear. Bracket g is provided in its aforesaid slottedportion and in the parts thereof both above and below the slot 7b with vertically registering apertures 2', both alike,

to wit, elongated, the central portion of each such elongated aperture being enlarged to form a bearing 2". i

A bracket is secured in some suitable position to the inside of the shutter.

The brackets and are adapted to be connected as follows: 70 and Z designate the fiat strip-like sections, overlapping each other, of an extensible arm. One section, 70 has straddling it and fitted thereto from the under side and suitably secured thereto a U-shaped bearing piece m in which is pivoted a cam '72 having a handle 0 for turning it so as in one position to clamp the sections together and in the other to release them. Between the sides or upstanding checks of the bearing piece on and between the cam and the section Z and having its ends widened, as at 79, so as to engage said sides or cheeks and thus be held in place, is a wear piece 9 to assume the wiping action of the cam. It will be obvious that the arm, thus provided with a clamping means, may be altered in effective length upon re leasing the cam, and that when it is so I altered and the cam made to bind theparts 7 released.

shank s of the T being-preferably rounded. This thus formed down-tui*ned free end'of'the section is of the arm isadapted to enter the apertures 2' in a certain position of the arm, as will be explained, and when in'that pos tion its shank s has a bearing in the bearings Usually, the free or down-turned end of the extensible arm 7cl will be received in the aperturesi of bracket 9; When it is so received the arm may oscillate in the bracket as the shutter is opened or closed, its parts or sections sliding on each other (the clamp being released) to permitnecessary change in the length of the arm. The shutter may be held against movement in any position to which it is swung by clamping the arm sections together by means of cam 0.

When the down-turned end of .arm 7c-Z is received in the apertures c of bracket "g, as

explained, it cannot work out of'thesame' by action of the wind or-be lifted out except in one position; to wit, when the shutter is fully closed, at which time 'only,it will be observed, will the T-head r of the arm coincide with apertures 71: in any other position of the parts said T-head is more or less oblique to the apertures and hence the latcral projections of saidT-head coact with the marginal portions of'the apertureand form an interlock preventing uplift of thearm and consequent release therefrom of the bracket. The shutter may therefore be partially bowed, and if the arm sections are duly clamped together no movement of the shutter can then be effected "from the outside.
